[Phpwebsite-developers] Temporary failure in name resolution

[Projet/Objet <li...@pr...>]

For testing, I finally sort of succeeded in installing the RC4 on one of my
servers.

I can browse the main page but when I enter my admin logins, after a very
long delay (something like 4-5 minutes) it returns me with a page packed of
errors such as this combo:

---------
Warning: php_network_getaddresses: getaddrinfo failed: Temporary failure in
name resolution in /home/mysite/public_html/fr/core/Text.php on line 414

Warning: getimagesize: Unable to open
'http://www.mysite/fr/mod/help/img/help.gif' for reading. in
/home/passages/public_html/fr/core/Text.php on line 414
---------

This is happening even if I have uploaded the latest Text.php file

Anyone would have a clue on what I should be checking?
Maybe I should erase this install and startover fresh?
